DAYS 1-5 (JANUARY 25-29)<\/p>\n\n\n\n
The upcoming storm system behaves as previously noted in terms of timing, coming in this afternoon and exiting early Thursday, with low pressure moving into the eastern Great Lakes and redeveloping right over southern New England before moving quickly seaward. Recent short range guidance trends have been consistently for a slightly weaker thrust of precipitation and slightly milder overall set-up, and after briefly considering erring on the side of “over-performance” before this trend got underway, I’m actually going to take the top edge off my initial snowfall estimate, which will appear in updated form in the detailed forecast below. Expect a little batch of very light to light snow to extend out from the approaching system that can put some flakes in the air but not likely have any real road impact sometime early this afternoon, favoring areas north of I-90 and west of I-95. The main batch of precipitation then arrives late in the day, before darkness falls for the western areas and at dusk or shortly after dark for eastern areas. For most it starts as snow, except the immediate coast and certainly the South Coast which have a much better shot at starting as a mix of snow and rain or even just rain. Before long, a definitive rain\/snow line, perhaps with a narrow ribbon of sleet along with it, will not only be apparent but will waste little time moving northward across the WHW forecast area during the evening hours, followed by a solid moderate to heavy swath of rainfall during the late evening and overnight hours. The system is moving along swiftly enough that I expect this area of rain to exit from west to east before dawn on Thursday, leaving us with a drier day, mild in temperature, with an increasing breeze to help dry of most cleared surfaces. With colder air returning Thursday night we will have to watch for areas of melt-water and puddles freezing up – typical wintertime stuff – so be aware of that later that night and early Friday. Friday’s weather itself looks fair with a little less wind as a small ridge of high pressure, centered to the south but extending northward, moves across the region. The wind picks up again on Saturday as that high slides offshore and a low pressure area moves quickly west to east across southeastern Canada. This low will drag a cold front across the region which may produce a few showers of snow, mixed precipitation, and maybe even rain to the south, during the morning and midday hours, based on current expected timing. But that frontal boundary doesn’t get that far south and east of us and lifts right back across the region on Sunday while another low pressure disturbance moves through the eastern Great Lakes, destined for a path north of our region late Sunday through early Monday. This will bring some light precipitation later Sunday or Sunday night, in the form of snow or mix to the northwest, mix or rain to the southeast, to be fine-tuned as we get closer to its occurrence.<\/p>\n\n\n\n
TODAY: Clouding up. Brief light snow possible north central to northeastern MA and southern NH midday or early afternoon. Snow\/mix\/rain arriving west to east late in the day, snow most likely inland, rain more likely coast. Highs 33-40. Wind NE 5-15 MPH.<\/p>\n\n\n\n
TONIGHT: Overcast. Snow\/mix\/rain transitioning to rain during the evening south to north, rain possibly heavy at times late evening into overnight, ending west to east pre-dawn. Snow accumulation before change-over from little or nothing in coastal areas to a coating to 2 inches away from the coast, with 2-4 inches possible in higher elevations of central MA and southwestern NH. Temperatures slightly rising to 35-42 southern NH and central MA, 43-50 most areas except over 50 South Coast and Cape Cod. Wind E-SE 10-20 MPH, higher gusts, shifting to SW along the South Coast with an area of variable winds right along the track of the new low center.<\/p>\n\n\n\n
THURSDAY: Clouds occasionally break for sun. Highs 40-47 except 48-55 South Coast \/ Cape Cod. Wind variable 5-15 MPH becoming W 10-20 MPH with higher gusts expected.<\/p>\n\n\n\n
THURSDAY NIGHT: Clearing. Lows 17-24. Wind NW 5-15 MPH, higher gusts.<\/p>\n\n\n\n
FRIDAY: Sun\/cloud mix. Highs 32-39. Wind NW 5-15 MPH, higher gusts.<\/p>\n\n\n\n
FRIDAY NIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH.<\/p>\n\n\n\n
SATURDAY: Partly sunny. Chance of a passing snow\/mix\/rain shower through midday. Highs 35-42. Wind SW 10-20 MPH, shifting to NW, with higher gusts possible.<\/p>\n\n\n\n
SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH early becoming variable, then S up to 10 MPH.<\/p>\n\n\n\n
SUNDAY: Increasing clouds. Chance of light rain\/mix southeast and mix\/snow northwest evening or night. Highs 38-45. Wind S up to 10 MPH.<\/p>\n\n\n\n
DAYS 6-10 (JANUARY 30 \u2013 FEBRUARY 3)<\/p>\n\n\n\n
Relatively weak disturbance (the one coming in late Sunday) exits early Monday January 30 with fair weather following through January 31. Continuing to watch the first few days of February for colder weather and a potential winter precipitation threat.<\/p>\n\n\n\n
DAYS 11-15 (FEBRUARY 4-8)<\/p>\n\n\n\n
Overall pattern looks a little colder with another storm threat around mid period.<\/p>\n","protected":false},"excerpt":{"rendered":"
